One of my competitors who I suspect had a part in me being slapped by Penguin is clicking on my adwords ads. Checking his IP host name area / town against his office address postdcode there is like 2 miles between the two (the host name area will cover 2 to 5 miles or maybe more I reckon) it seems to be the same guy. I reported it to google - all the good that will do. As I said, I suspect this guy to be part of the reason why I am having to pay for adwords. What would you do? Retaliate or let karma fuck him up? Any suggestions what to do?
